﴿ قُل لَّوْ كَانَ ٱلْبَحْرُ مِدَادًۭا لِّكَلِمَٰتِ رَبِّى لَنَفِدَ ٱلْبَحْرُ قَبْلَ أَن تَنفَدَ كَلِمَٰتُ رَبِّى وَلَوْ جِئْنَا بِمِثْلِهِۦ مَدَدًۭا ﴾

“SAY: "If all the sea were ink for my Sustainer's words, the sea would indeed be exhausted ere my Sustainer's words are exhausted! And [thus it would be] if we were to add to it sea upon sea."”

Say ‘If the sea in other words if its waters were ink midād is what one writes with for the Words of my Lord Words that testify to His laws and His marvels such that these Words are written with it the sea would be spent in recording them before the Words of my Lord were spent read as tanfada or yanfada even though We brought the like of it namely the like of the sea as replenishment’ in order to add it to the other sea it would also be spent while they God’s Words would not be exhausted madadan ‘as replenishment’ in the accusative because it is a specification.
